1 / 3 page EV0042 1x, 1.5x, 2x High Efficiency Charge Pump 4 White LED Driver Evaluation Board EV0042 Rev. 1.5 www.MonolithicPower.com 1 10/27/2005 MPS Proprietary Information. Unauthorized Photocopy and Duplication Prohibited. © 2005 MPS. All Rights Reserved. The Future of Analog IC Technology TM TM GENERAL DESCRIPTION The EV0042 is an evaluation board for the MP1519, a fully automatic driver for powering four white LEDs, with up to 4V forward voltage, from a single Li-Ion or three NiMH cells. The driver performs all of the sensing and control to run the LEDs at an optimum charge pump ratio for efficiency without an expensive inductor. The driver allows PWM operation to support brightness control. The tiny 3mm x 3mm QFN16 package and small external capacitors allow for the most compact white LED solution available. ELECTRICAL SPECIFICATIONS Parameter Symbol Value Units # of WLEDs 4 Input Voltage VIN 2.5 – 5.5 V LED Current ILED 20 mA FEATURES • 2% LED Current Matching • High Efficiency (>93%) • Current Source Outputs • No Ballast Resistors Required • 1x, 1.5x and 2x Automatic Modes • Constant Frequency Operation • Automatic LED Detection • High and Low Frequency PWM Capability • 2.5V to 5.5V Operation • Less than 1µA Leakage during Shutdown • Detects Changes in Battery Level • No External Schottky Diode Required • Soft-Start and Soft Switching Operation APPLICATIONS • Cell Phones • PDA or Hand Held Computers • White LED Application at 3.6V Supply “MPS” and “The Future of Analog IC Technology” are Trademarks of Monolithic Power Systems, Inc.
